The heartwoods of two species of South African
Euphorbiaceae have been chemically investigated.
From Cleistanthus schlechteri three new diterpenes
possessing the hitherto unknown ent-isopimara-8(14),15-diene
skeleton ...

Equilibrium and kinetic data for the solvent extraction of
germanium by three impure commercial 7-alkylated-8hydroxyquinoline
extractants which vary in structure at the 7alkyl
group, are evaluated in order to elucidate ...

The alkylation of 2-methylcyclohexanone imines using methyl acrylate has
been investigated with a view to optimising the reaction conditions.
The mechanism of this alkylation reaction has been investigated and it has
been ...

Reaction of the pyrrolidine dienamines of ~1,8a-2-octalones with methyl vinyl
ketone is complex. In methanol as solvent, the reaction occurs primarily with
the linear dienamine isomer and results in annulation of the ...

An electrochemical investigation of the corrosion of iron and Fe18Cr based stainless steel alloys was
undertaken with particular emphasis on the nucleation and growth of surface films.
Chronoamperometry was shown to be ...

The theoretical and experimental work in this thesis is primarily aimed at
i) the quantification of the strengths of a number of hydrogen bonded
systems, and ii) exploring the relationships that exist between the ...
